Re: Please a parameter to disable undo, like _disable_logging

Direct-path or APPEND inserts do avoid undo, except for the space-management
stuff in the data dictionary.

Direct-path loads data into TEMPORARY segments which, upon successful
completion of the load (a.k.a. commit), are converted into DATA segments.
Upon unsuccessful completion of the load (a.k.a. rollback), the TEMPORARY
segments are simply dropped.
